Extra-high Voltage Outdoor Power Station Surge Protection Device

Description:

Porcelain Surge Arrester

Main features: It adopts double sealing structure, the core encapsulates by molded silicone rubber which completely solves the sealing problem of porcelain housed products.
It has a two-way pressure release structure.
Its core component ZnO varistor has good pressure ratio, consistency, large flow capacity and high reliability.
E creepage distance of porcelain housed products is wide which is suitable for IV level heavy pollution areas.

Specifications:

Rated voltage: 444KV
Nominal discharge current: 20KA
